Old buildings in urban centres are a cultural heritage to be preserved as a link between past and present. They represent the identity of the region and the place, and cannot be renovated using “replicable” energy solutions like standard existing buildings. In addition, the integration of renewable energies into old buildings may also be subject to specific authorisations or exemptions depending on the architectural conservation measures in place for the building in question.

• Develop a platform to help with the energy renovation of buildings with heritage value in town and village centres, including documentary resources on a website and a cross-border calculation tool compatible with existing geoportals.​
• Provide feedback on the cross-border geoportal and share best practices​
• Provide a tool for estimating the potential for energy renovation (pre-audit tool) that can be connected to geoportals to assess the possible synergies between renovation of the building envelope, replacement of heat production and production of renewable energy in these buildings.​
• Use the historeno approach & platform as a tool for dialogue within public authorities (e.g. in the French-speaking cantons of Switzerland) between different departments such as energy or heritage.​
